Aims: Milk is rich of nutrients that are necessary for the growth of various microorganisms. The aim of the present study was to evaluate the microbial quantity and quality of the raw cow’s milk sold through street trading in Meknes, Morocco, and to study the variation and seasonal relationship of microbial diversity during the four seasons of the year. Methodology and results: Raw cow’s milk samples were collected randomly between May 2015 and April 2016 from 3 street trading sale points, two popular neighborhoods (station 1 and station 2) and one popular market, and they were analyzed microbiologically. The results showed that the contamination rates of Total Plate Count (TPC), total coliforms, fecal coliforms, lactobacilli, lactococci and yeasts and molds were 8.8×108 CFU/mL, 8.9×105 CFU/mL, 2×103 CFU/mL, 4.6×108 CFU/mL, 7.5×108 CFU/mL and 4.1×103 CFU/mL, respectively. Moreover, Escherichia coli, Staphylococcus aureus, Clostridium perfringens and Listeria monocytogenes were detected in 66.67% (24/36), 75% (27/36), 36.1% (13/36) and 19.44% (7/36), respectively, while Salmonella was not detected in this study. Conclusion, significance and impact of study The highest microbiological count in raw milk samples was found in summer, while the lowest was detected in winter (p˂0.005). Therefore, the quality of milk marketed in Meknes region of Morocco is deteriorated due to the lack of good hygienic conditions of raw cow’s milk sold through street trading.

OBJECTIVES: Diabetes is one of the most life-threatening chronic metabolic disorders and is considered a global health problem due to its prevalence and incidence. In Morocco, several herbal preparations are utilized to treat this disease. For this reason, the current study aimed to identify and to collect data about the medicinal plants utilized in folk medicine for the treatment of diabetes in the Beni Mellal region of Morocco. METHODS: An ethnobotanical survey was carried out among 400 herbalists, competent villagers and traditional healers from the Beni Mellal region through direct interviews using a semistructured questionnaire. RESULTS: Forty-five medicinal plants belonging to 25 families were identified for their use in diabetes treatment. Interview results showed that the most frequently used plants were Olea europaea, Salvia officinalis, Allium sativum and Trigonella foenum-graecum, with a relative frequency of citation values of 24.3%, 23.0%, 22.5% and 20.5%, respectively. Moreover, in this study, the Fabaceae family was the most commonly reported plant family, and the leaves and roots were the most commonly used parts, for the treatment of diabetes. CONCLUSION The Beni Mellal region of Morocco has an important floristic biodiversity of plants used to treat diabetes in traditional medicinal practice. This result provides a good database for pharmacological screenings in the search for plant-based antidiabetic medications.
